Answer: 9 pieces of candy have been eaten.
Explanation:
To find the number of pieces of candy that have been eaten, we need to determine how many pieces are left in the box.
The box of candy holds 24 pieces when first opened. We are told that the box is now 3/8 full.
To find how many pieces are left, we can calculate the amount of candy that is still in the box.
Since the box is 3/8 full, this means that 5/8 of the candy has been eaten.
To find the number of pieces that have been eaten, we can subtract the amount of candy that is still in the box from the original number of pieces in the box.
5/8 of the candy has been eaten, so the amount of candy that is still in the box is 3/8 of the original number of pieces.
We can calculate this by multiplying 3/8 by 24:
(3/8) * 24 = 9 pieces
Therefore, 9 pieces of candy have been eaten.
